Old Cobblers Farm™ Wicked Growth Legumes Fertilizer
Product Overview
Description
Wicked Growth Legume Fertilizer is specifically formulated for beans, peas, lentils, and other nitrogen-fixing crops with unique nutritional requirements. The low-nitrogen 5-10-10 formula complements the natural nitrogen-fixing ability of legumes while providing elevated phosphorus and potassium for prolific pod production.
Legumes form a symbiotic relationship with rhizobia bacteria that fix atmospheric nitrogen. High-nitrogen fertilizers suppress this beneficial process. Wicked Growth Legume Fertilizer's low nitrogen formulation encourages maximum nitrogen fixation while phosphorus supports nodule formation and potassium drives pod development.
Whether growing bush beans in a raised bed, pole beans on a trellis, or cover crop legumes for soil improvement, this specialized formula maximizes both your harvest and the nitrogen-building benefit legumes provide.
Highlights
• Low N supports nitrogen fixation
• High P-K for pod production
• Promotes healthy root nodules
• Builds soil nitrogen naturally
• Perfect for all legume types
The Science Behind It
How It Works
This legume-specific formula provides low nitrogen with elevated phosphorus and potassium, respecting legumes' natural nitrogen-fixing ability. Rhizobia bacteria in legume root nodules convert atmospheric nitrogen into plant-available forms, reducing the need for supplemental nitrogen. The higher P-K ratio supports root nodule development, flowering, and pod formation. Applied at planting or early growth, this formula establishes strong foundations without suppressing biological nitrogen fixation.
The Science
Legumes form symbiotic relationships with Rhizobium bacteria that colonize root nodules and fix atmospheric N₂ into ammonia through nitrogenase enzyme activity. Excess soil nitrogen suppresses nodulation and nitrogen fixation—hence the low 5% N in this formula. Phosphorus directly supports nodule development and ATP production required for the energy-intensive nitrogen fixation process. Potassium regulates nodule function and supports pod and seed development, where legumes concentrate nutrients.
Nutrients Available
5% Total Nitrogen – Gentle support without suppressing natural nitrogen fixation. 10% Available Phosphate (P₂O₅) – Powers nodule development and energy production for nitrogen fixation. 10% Soluble Potash (K₂O) – Enhances flowering, pod formation, and disease resistance. Supports beans, peas, lentils, and all legume family crops.
How to Apply
1-2 lbs/100 sq ft every 4-6 weeks. Severe deficiency: 2-3 lbs initially.
1
Action:
Survey garden bed and note deficiency symptoms. Map high-need zones.
Pro Tip:
Sandy areas and fruiting sections need more K than shaded areas.
Avoid:
Don't leave granules on surface in hot weather - damages plants.
2
Action:
Calculate 1-2 lbs per 100 sq ft. For 10x20 garden (200 sq ft), use 2-4 lbs.
Pro Tip:
Weigh fertilizer on kitchen scale. One cup 0-0-60 weighs ~0.5 lb.
Avoid:
Don't exceed 2 lbs per 100 sq ft per application. Split heavy doses.
3
Action
Broadcast granules evenly across soil surface. Work into top 2-3 inches with cultivator.
Pro Tip:
Sandy areas and fruiting sections need more K than shaded areas.
Avoid:
Don't spread on windy days - granules drift causing uneven application.
4
Action
Water thoroughly with 1-2 inches to dissolve granules and move K into root zone.
Pro Tip:
Incorporation prevents salt buildup and gets K to roots faster.
Avoid:
Don't leave granules on surface in hot weather - damages plants.
